Improvement in door-checks



este effin,

wia sa county of St. Louis Vand. kState of Missouri, have invented a certainCheck for Doors, of which the following is a specication. y y

Nature and Object ofthe Invention. i y My check consists of an armor lever, which is pivoted at the bottom of the door on the side thereof', and whose free end carries a rubber roller, which is made to come iucontact with the oor or carpet to keep the door in anyvdesired position. y

y `.Descrption of the Accompanying Drawing. Figure 1 is aperspective view of the lower portion of a doorwith my check applied thereto.

i Figure 2 is a section through a portion of the door and through `the check at the axes, showing the latter full size for a common house-door.

GeneralfDescriptonl,

A is the lower portion of a door, and

` B is thepivoted leyercr. arm, which may be pivoted to the door bya common wood-screw, O.` i

Between the lever B and the door isa washer, D,

of leather or India rubber, whose friction against the y door and lever is sucient to retain the latter in any position i'n which it may be placed. v

Pivoted to the free endlof. the lever, by a pivot, e,

1 is an India-rubberlroller, E, which is brought in cony tact with the Vdoor Aor carpet to hold the door in. any

` desired position.

` Letters Patent No. 112,6711, datedV 'March 14, 1871.

` lM-Pgovl-:MENT IN noon-CHECKS.

` The Schedule refen-ed to in these Letters Patent and making part of the same.

A The axes of the roller and lever, namely, the screw G and pivot e, are at right angles with the face of the door, so that the lever and roiler turn in planes parallel with the side of the door, and pressure against the f door has no tendency to move either the lever or roller on its axis.

When in action the check is nearly perpendicular, as s'hownin full lines in'fig. 1.

, The operation of the check is as follows:

The check is ordinarily kept in the position shown by dotted lines in vfig. 1, namely, with the .free end thrown up, to remove the roller from contact witlrthe Hoor or carpet and the door is freeto swing. When put in use the door is Opened to the position required, whether partly or wholly opened, and ,the lever depressed with the foot to bring the roller in contact with the carpet; the door will then beheld to its position. Y

Claim..

l claim as my invention-- u l TheV door-check, consisting of a lever, B, carrynga roller, E, the axes C cof which are perpendicular to the face of the door, so that the movement of the latter will not act to raise the lever nor rotate'the' roller, all substantiall y as described.
